EnVision Environmental Education is proud to introduce the Build Your Own Groundwater Simulator Kit #1. This Kit is designed specifically for science clubs, earth science classes or as a science project on groundwater and groundwater contamination. Kit contains all the parts shown in the photos above and listed below. Due to shipping restrictions, you must supply your own 10-gallon aquarium and sealant (aquarium glue or silicone sealant). Both of these items are readily available at large department stores, home improvement stores or local pet stores. Finished product is a basic groundwater flow model with recirculating pump, including 4 wells, sand and clay layers and a cross-section of a lake or stream. Instruction manual includes some basic experiments and calculations. Kit should be used under adult supervision and will need approximately 24 hours of drying time between initial assembly of aquarium and acrylic (with sealant) and the second phase of adding sand and clay.
